AUXILIARYKHEATER.

SPECIFICATION forming part of Letters Patent No. 518,864, dated April 24, 1894.

Application filed March 6, 1893.

To all whom it may concernr Be it known that I, EDWIN SHEPPARD, a cltizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Auxiliary Heaters, of which the following is a specification.

My invention relates to certain improvements in auxiliary heaters for application to the pipes of stoves or furnaces either in the room in which the stoveis placed or in a room adjacent thereto.

The object of my invention is to simplify the construction of heaters of this class and to so make them, that the parts can be readily detached so that the interior of the heater can be cleaned without interfering with the piplng. This object I attain in the following manner, reference being had to the accompanying drawings, in which Figure 1, is a longitudinal sectional view of my improved heater. Fig. 2, isa perspective v ew. Figs. 3 and 4, are detached perspective views. Fig. 5, is a view showing a series of heaters united. Fig. Q, is a sectional view lllustrating the application of my improved heater to a vertical pipe. Fig. 7, is a face View showing the heater inclosed within a casing adapted to beset in the wall.

A is the casing made preferably of sheet metal and in the present instance, as shown in the drawings, is quadrangular, but it will be understood that it may be in any form desired without departing from my invention.

a is an inlet opening and a is an outlet opening and adapted to the flanges b b are the pipes B B extending from the stove or furnace to the chimney, the openings at a can be of different diameters according to the size of the pipes B B.

D is a cap snugly fitting the casing A so as to prevent gas from entering the room and depending from this cap are a series of tubes (1 passing through the cap and secured thereto in any suitable manner and secured to a base plate D which snugly fits the interior of the lower portion of the casing preventing gas from escaping between the base plate and the casing. The hot air from the stove passes into the casing through'the pipe Band circulates around the tubes d, thus heating them and then passes out through the pipe B to the chimney; the heating of the pipes (1 causes Serial No. 46,926. (N0 model.)

the circulation of air through the pipes as indicated by the arrows Fig. 1, consequently the air in the room in which the auxiliary heater is situated is heated to a certain degree.

By making the auxiliary heater as clearly shown in Figs. 3 and 4, that is having the tubes secured to the top and bottom plates and the whole detachable from the casing, the interior of the casing can be cleaned as well as the tubes as all that is necessary is to lift the cover D and remove the parts 7 as shown clearly in Fig. 4, when these parts are cleaned all that is necessaryis to insert them in the casing.

I-preferably make the auxiliary heaters in small sections and if necessary use a series of these sections as shown clearly in Fig. 5, the sections may simplybe coupled together and suspended by the piping or suspended from the ceiling by wires, but I prefer, when using a series, to mount them upon a table or platform E supported by a stand F mounted on the floor, this stand can be adjusted so as to accommodate stoves or pipes of difierent height. I prefer to form feet on the casing so as to allow the air free access to the interior of the heater.

The above described apparatusrefers particularly to horizontal piping but where vertical piping is used I prefer the device shown in Fig. 6, which is simply the casing arranged on an incline so that the heat will pass up directly through the casing and the air from the room will traverse the tubes at an incline. The cover plate, tubes and bottom plate are arranged in the same manner, as shown in Fig. 1, so that it may be readily removed and cleansed.

In Fig. 7, I have shown the device'shown in Fig. 6 duplicated and inclosed within a box having an open front, this is especially applicable for insertion in walls of buildings Where the fines are in the walls, the front of the box may be provided with ornamental grill work or a register.

The device shown in Figs. 1 and6 may be provided with means whereby a Water vessel may be adapted to the heater so as to moisten the air.

I claim as my invention- 1. The combination in an auxiliary heater,

of the casing, inlet and outlet for the gas or hot air, with a cover plate, air pipes and bottom plate secured together and removable from the casing, substantially as described.

2. The combination in an auxiliary heater, of the casing, inlet and outlet therefor, a cover plate and tubes secured together and removable from the casing, with a support for the casing independent of the connecting pipes, substantially as set forth.

3. The combination in an auxiliary heater, of the inclined casing, vertical hot air or gas passages with pipes, cover plates and bottom plate, secured together and adapted to the in.- clined casing, substantially as set forth.

4. The combination in an auxiliary heater, of the series of casings connected together,

inlets and outlets therefor, removable tubes and cover plates adapted to each casing, with a support upon which the several casings rest, substantially as set forth.

5. The combination in an auxiliaryheater, of the casing, inlet and outlet for the gas or hot air, with a cover plate overlapping the casing and sealed, a flanged bottom plate adapted to snugly fit in the casing, tubes extending through and attached to both the top and bottom plates whereby the tubes and plates can be removed bodily from the casing, substantially as set forth.
